Pedal Stops
These are necessary to avoid over loading the control cable when the valve reaches the end of its travel. These stops also ensure that the operators body weight is never supported by the cables.
Tools required 2x 9/16" Spanner
Pedal Stop Adjustment - Drive Wheels
Loosen lock nut on pedal stop (9/16” spanner) and wind in pedal stop bolt. Move the pedal to full travel in one direction so the valve spool reaches the end of its travel.
Note: Use a wooden block or a hammer handle to lever the pedal.
Set the pedal stop until it contacts the platform floor. Wind out a further half turn. While holding the pedal stop re-tighten the lock nut. Repeat process for other direction.
Pedal Stop Adjustment - Boom Lift
The lift or front stop on the pedal is the same as above step. The rear stop sets the lowering speed of the platform. Set the pedal stop so the boom is just starting to lower as the stop hits the floor.
The platform lower speed will increase with weight of the operator in the platform. Caution: Setting the speed to high will cause the platform to judder when lowering.
